EMBROIDERI'NG ATTACHMENT FOR KNITTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 768,093, dated August 23, 1904. Applicatioli'filed September 17, 1903. Seria1N0. 173,523. (No model.)

To all whom, it Hertz concern:

Be it known that LEDUARD RICHARD THIER- FELDER, a subject of the Emperor of Germany, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new anduseful Improvements in Embroidering Attachments for Knitting-Machines, of which thefollowing is'a specification.

My invention relates tomechanism for embroidering knit fabrics, most commonly stockings, with silk or other suitable material contemporaneous'ly with the operation of knitting the fabric to be embroidered.

I accomplish my invention by devising mechanism consisting, most essentially, of tubes serving as conduits for embroideringthread, provided with means for carrying such conduits with their threads alternately back and forth, behind, between, and around in front of the fabric-forming needles of the machine, together with a pattern-wheel and connecting devices extending from the embroidering-thread conduits into engagement with the pattern-wheel.

I have shown my attachment applied to and to some extent incorporated into a full-fashioned flat knitting-machine of the cotton type, having its fabric-forming needles arranged substantially vertically and all operative in the same plane. The machine to which I have "shown it as being applied is very large and complicated, and I have therefore purposely had omitted from the drawings and description thereof nearly everything excepting the devices for producing such portions of stockings as are customarily embroidered, (the leg and instep portions thereof.) and with such knitting devices I have connected my embroidering attachment. Considerable portions of the narrowing mechanism of the machine have been shown in the drawings, as they could, not Well be omitted without representing the machine too much mutilated to illustrate my invention to the best advantage.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a top plan view of an end section of i a knitting-machine, which, however, for convenience, Wlll generally be referred to hereinafter as a knitting-machine provided Withand others omitted therefrom. Fig. 3

Fig. 2 is a front elevation of the same with some parts added thereto is a left-hand end elevation of the machine substantially as it appears when complete in all its parts. Fig. 4 is a section at the dotted line 4 4 in Fig. 20f parts there shown. Fig. 5 is a section at thedotted line5 5 in Fig. 2 of parts there shown. Fig. 6 is a front elevation of an end section, the end opposite to that shown in Fig. 1, of the machine with parts omitted and other parts broken away. Fig. 7 is a rear elevation of parts of the same section of the machinethat are shown in Fig. 6. Fig. 8 is a sec- 5 shown. Fig. 9isan enlargeddetail view ofthe pattern-wheel of the embroidering mechanism of the machine with parts for operating the same and other parts cooperating therewith- Figs. 10 to 14:, inclusive, are enlarged detail views of cam devices for longitudinally sliding in one direction the rock-shaft carrying the embroidering-tubes of the embroidering attachment of the machine. Fig. 15 is an mechanism of the machine, showing one of the embroidering-tubes of the embroidering attachment thereof and the longitudinallysliding rock-shaft which carries-all of such tubes. Fig. 16 is a diagrammatic View of a group of three knitting-needles of the machine, showing an embroidering-tube carrying a thread of embroidering material around the central needle of such group. Figs. 17 and 18 are enlarged detail views of two slightly different species of sinker-slides belonging to the knitting mechanism of the machine and shown in operative connection therewith in Fig. 15. Figs. 19 and 20 are enlarged detail views showing a few rows of stitches of the fabric produced by the knitting mechanism of the machine. Fig. 21 is a detailed View showing the product of the machine having an ornamental pattern embroidered thereon. Fig. 22 is an enlarged detail top plan view of a part of the. longitudinally-sliding carriage shown in Figs. 1 and 9 of the embroidering mechanism of the machine with its cover removed. Fig. 22 is a section at the dotted line 22 in Fig. 22 of parts there shown. I00

Fig. 23 is a diagrammatic view of a group of three knitting-needles of themachine represented as engaged in the operation of knitting a piece of fabric like that shown in Fig. 21 with one of the embroidering-tubes deliveringa loop of embroidering-silk to the middle needle of the group in order that it may be knit into the fabric at the next descent of the needles to knit another row of stitches thereon. Fig. 23 is a diagrammatic view showing the path traveled by the free end of each embroidering-tube while placing a loop of embroidering material about one of the knitting-needles of the machine. Fig. 24 is an enlarged isometrical detail view illustrating one means of establishing operative connection between the pattern-wheel and embroidering-tubes of the embroidering mechanism of the machine. Fig. 25 is a like View showing another means of accomplishing the same thing.

Like characters of reference indicate cor responding partsthroughout the several views.

----Figs.'2 and 6, meshing with the pinions 7 and 9, respectively, of thedrivingshaft, and numerous cams for operating the knitting, narrowing, and other mechanism of the machine. The above mentioned cams are mounted generally in pairs on the cam-shaft 10, with the adjacent body portions of each pairin close contact and rigidly secured together.

13, 1 1, 15, 16, and 17, Fig. 3, are rock-shafts extending the whole length of the machineframe and mounted in bearings therein. From these rock-shafts arms, fast thereto and having rollers mounted in the free ends thereof, project the peripheries of such rollers down into contact with or into the paths of the peripheries of the cams on the cam-shaft 10. The width of the periphery of each of such rollers is about equal to the width of. the periphery of each of the cams composing one pair of the several pairs of cams mounted on the cam-shaft 10. The cam-shaft 10 may be shogged, at predetermined times or at will,

endwise sufiiciently to bring either eam of any one pair thereon under and into engagement with the roller mounted in the free end of the arm projecting downward and nearest thereto. This movement is insuliicient to take out of mesh the gears 9 12 and 7 l l.

29 is also a longitudinally-slidable sinker having a thread carrying and evening notch 30 in and a linger-like portion 80 projecting from one end thereof and terminating at its other end in a transverse actuating-lug Ell, somewhat longer than the corresponding lug 28 of the sinker 26. One sinker, 29, is slidably seated in each remaining groove 25 in the part 23-that is to say, a sinker 26 is set into a groove 25 and then a sinker 29 is set into the next adjacent groove 25, and so on until the grooves 25 are all occupied by such alternating sinkers.

32 is a sinker-jack mounted on the horizontal stationary rod-bearing ill-1 by means of the transverse slot 34- therein. The jacks 32 are located immediately behind the sinkers 26, and the edges of their free ends 35 rest against and are constantly in contact with the rear ends thereof.

36 is a sinker-controlling bar as long as the machine and having a rectilinear groove 87 in the under side thereof to admit the lugs 31 of the sinkers 29, which are continuously in engagement therewith. The lugs 28 of the sinkers 26 are also engaged by the groove :37 in the sinker-controlling bar 36 to draw such lOO \ plained hereinafter.

sinkers 26 backward each time after they have been advanced by their jacks 32, as will be ex- 38, Figs. 3 and 15, is a horizontal track as long as and rigidly connected with :the frame on the sides nearest to the observer of the free ends 41 thereof to press against and slide the jacks 32 and their sinkers 26 forward at proper times.

42 is a comb as long as the machine-frame, with which it is rigidly connected, and provided with transverse vertical guide-teeth 43, between two of which each jack 32 projects somewhat loosely.

44 represents knocking-over bits, which are equal in number to and lie in the same vertical planes with the slidable sinkers 26 and 29 and are rigidly clamped against the bottom of the bed-piece 23 by means of the long bracket 45 and screws 46. I

47 is a stationary keeper which serves to maintain the slidable sinkers 26 and 29 all at the same level in their grooves 25 in the bedpiece 23.

48 is the knitting-thread carrier of the machine and is connected intermediately with the slidable carriage 39 on the track 38.

49, Fig. 4, is an arm rigidly securedby one end to the rock-shaft 14 and jointed by the other end and by means of the pivot 50 to the needle-bar 18.

51 is an arm rigidly secured by its upper end to the rock-shaft 14 and having a roller 52 mounted on the lower end portion thereof.

53, Figs. 2 and 4, is a cam on the cam-shaft 10, which, acting through the roller 52, arm 51, rock-shaft l4, and arm 49, carries the needle-bar 18 and its needles 19 alternately up and down at each rotationof such shaft 10 while the operation of knitting is going on.

54 is a tension-spring connecting the lower end of the arm 51 with a fixed bearing 55 on the frame 1 and serving to maintain the roller 52 in engagement with the cam 53.

56, Fig. 15, is an arm rigidly secured by one end to the bottom of the sinker-controlling bar 36. r

57, Figs. 4 and 15, is an arm rigidly secured by one end to the rock-shaft 15.

58 is a linkjointed by its upper end and by means of a pivot 59 to the free end of the arm '56 and by its lower end and by means of a pivot 60 to the free end of thearm 57 The rock-shaft 15 is actuated by means of a cam a, Fig. 6, on the cam-shaft 10 and an arm 6, fast to such rock-shaft 15 and carrying a roller 0 in its free end projected against such cam a on the cam-shaft 10. The rock-shaft15, so actuated and itself acting through the arm 57,

64 is an arm rigidly secured by its upper end to the rock-shaft l6 and having a roller 65 mounted on the lower end portion thereof.

66, Figs. 2 and 4, is a cam on the cam-shaft 10, which, acting through the roller 65, arm 64, rock-shaft 16, arms 61 and 62, moves the sinker-controlling bar 36 alternately forward and backward at each rotation of such camshaft 10 while the operation of knitting is going on.

67 is a tension-spring connecting the lower end of the arm 64 with a fixed bearing 68 on i the machine-frame and serving to maintain the roller 65 in engagement with the cam 66. 69, Fig. '6, is an arm rigidly secured by its upper end to the rock-shaft 13.

70, Figs. 6 and 15, is a link jointed by one end and by means of a pivot 71 to the arm 69 and by its other end and by means of a pivot 72 to the lower edge of needle-bar 18 produced.

73, Fig. 6, is a cam on the cam-shaft 10. 74 is an arm rigidly secured to and projecting transversely from the arm 69.

75 is a roller mounted on the free end of the arm 74 and engaging the cam 73 .on the shaft 10. j

76 is a tension-spring serving to maintain the roller 75 in engagement with the cam'73. At each rotation of the cam-shaft 10 the cam 73, Fig. 6, acting through the roller 75, arm 69, and link 70, swings the upper edge of the needle-bar 18, Fig. 15, first toward and then from the edge 24 of the bed-piece 23, as

indicated by'the double arrow 00, for a purpose to be explained hereinafter.

7 7 Fig. 4, represents vertical arms (one only being shown) rigidly secured to the angle-bar 22 and having four rectangular openings 78 therein serving as slideway's for parts to be described hereinafter.

79 and 80, Fig. 1, are rectangular rods, ap-

proximately as long as the machine-frame, slidably mounted in. the openings 78 in the vertical arms 77, Fig. 4. The rod 79 supports the carriers 48, Figs. 4and 15, that conduct and pay out the threads that are to form the foot and leg portions'of the stockings being knit, and.the remaining three rods, 80, conduct and pay out the threads employed in forming the heels thereof. The rods 79 and 80 are allintermediately and rigidly connected with-the slidable carriage39, Figs. 3, 7, and, 15 on the track 38 by connecting means therefor (not shown) projecting upward from such carriage 39 into engagement with such rods 79 and 80.

81, Fig. 1, represents screw-stops for regulating the travel (longitudinal reciprocations) of the rods 79 and 80. The other end of the machine is also provided with such stops. (Not shown.)

82, Figs. 6 and 7, is a short shaft mounted in' bearings in the bracket 83 and on the bar 3* of the machine-frame.

84, Fig. 6, is a bevel gear-wheel fast mounted on the end of the shaft82 nearest to the observer.

85 is a bevel-pinion fast mounted on the shaft 10 and meshing with the bevel gearwheel 8 1.

86, Figs. 6 and 7 is a cam fast mounted on the end of the shaft 82 opposite to that on which the gear-wheel 8 1 is mounted and par allel thereto.

87, Fig. 7, is an arm jointed at its lower end and by means of a pivot 88 to the hangerbearing 89 on the bar 3 of the machine-frame.

90 is a pitman jointed at one end and by means of a pivot 91 to the carriage 39 and at its other end and by means of a pivot 92 to the upper end of the arm 87.

93 is an arm jointed at its upper end and by means of a pivot 9. 1 to the upper end of the tower-bearing 95 on the bar 3 of the machineframe.

96 is a link jointed at one end and by means of a pivot 97 to the arm 87 at a point between its ends and at the other end and by means of a pivot 98 to the lower end of the arm 93.

99 and 100 are rollers mounted on transverse rigid stud-bearings 101 on the link 96 and are alternately engaged by the cam 86 at each rotation thereof. Each rotation of the bevel gear-wheel'8 1 and the cam 86 slides the carriage 39 and all the parts carried thereby back and forth once.

Disregarding all movements of the machine parts, excepting only those required to produce such portions of stockings as are customarily embroidered that is, the leg and instep portions thereof its mode of operation, supposing power to be applied to the shaft 1 and communicated thence to the respective devices required to be actuated in order to produce such portions of stockings as are above proposed, will be as follows: The knitting-thread carrier 48 will pay out a thread (Z, Figs. 4; and 15, transversely across the upper edges of the finger-like portions 27 n and 30, Figs. 15, 17,

and 18, of the sinkers 26 and 29. As such thread is thus payed out the carriage 39, being slid along its track 38, forces the camsurfaces (not shown) on the portions 11 of the fingers 40 against the upper and free ends of the jacks 32, which are thereby impelled against and caused to slide all the sinkers 26 forward until the notches 27 therein engage the thread d and press it transversely against and between every alternate needle 19. immediate] y thereafter the cam 66, Fig. 1, acting through the roller 65, arm 64, rock-shaft 16, and arms 61 and 62, carries the sinker-eontrolling bar 36 and all the sinkers 29, Fig. '15, in engagement therewith forward until the notches 30 therein also engage the thread 1 and press it transversely against and between every remaining alternate needle '19, the notches 27 and 30 in the. sinkers 26 and 29 then all being and lying in and coinciding with one and the same straightline, and thereby serving to maintain the thread d tautly and evenly against and between all the needles 19 of the machine. 'llhereupon theeam 53, Fig. 4c, coaeting with thespring 51 and roller 52 and through the arm 51, rock-shaft let, and arm 49 lowers the needle-bar 18, Fig. 15, with its needles 19, until the beards 26 thereon are opposite to the edge 2-1 of the bed-piece 23, when the thread (i will be engaged by the hook portions (Z of such needles 19. Then the cam 73, Fig. 6, eoaeting with the spring 76 and roller 75 and through the arm 69 and link 70, Fig. 15, swings the upper edge of the needle-bar 18 toward the edge 24 of the bed-piece 23 until the beards 20 of the needles 19 come into eontaet with and are closed by the edge 21 thereof. The cam (I, Fig.6, eoaeting with a spring (not shown, but like the springs 51 aml 67, Fig. 41) and roller 0 and through the arm 0, rock-shaft 15, arm 57, Fig. 15, link 58, and arm 56, next imparts a downward movement to the sinker-controlling bar 36 until the groove 37 therein engages the lugs 28 of the sinkers 26. Then the cam 66, F'g. 1, eoacting with the spring 67 and roller 65 and through the arm 64:, rock-shaft 16. arms 61 and 62, moves the sinker-controlling bar 36, and therethrough slides all the sinkers 26 and 29 backward to their farthest limit of travel, as in Fig. 15. Immediately thereafter the same instrumentalities that are enumerated above as having lowered the sinker-controlling bar 36 will raise it to the position shown in Fig. 15, thereby releasing the sinkers 26 and leaving them free to be again slid forward by the jacks \Vhile the operations just described were in progress the needle-bar 18 continued its downwad course until the loops (Z of the needles 19 had descended between the knoekil'ig-over bits 1 1 and cast ofl the previous loops over the new loops. Then the same instrumentalities that swung the needle-bar 18 toward and its needles .19

against the edge 2 1 of the bed-piece 23 will swing it away from the same and to the position shown in Fig. 15, it being understood also that the same instrumentalities that lowered the needle-bar 18 and its needles 19, as set forth above, have restored such parts to the positions, Fig. 15, that they were assumed to occupy at the outset of thisdescription.

(6, Fig. 19, represents stitches in enlarged A, Fig. 1, is a rod, serving as a track for 1 parts to be described hereinafter, immovably mounted in the brackets A on the angle-bar 22, Fig. 3. A Fig. 9, is another and shorter 'rod, serving the same purpose as the rod A,

The longitudinally-reciprocating movements of the shaft B and the parts carried thereby are controlled by the joint operations of a pattern-wheel (not yet described) acting through either of the pattern-transmitting tingers A A A, the arm A, the disk B connected therewith, and the disks 13 B and the spring B Figs. 1 and 2. The oscillatory or rocking movement of the shaft B is sufiicient to swing the free ends of the embroideringtubes B between and a little higher up than the upper ends of all of the knitting-needles 19 of the machine.

Each rotation of the cam C when in engagement with and acting through the roller (7, lever 0. and arms (3 Choseillates the roek-shal'l'. B in the direction indicated by the arrow 1 in Fig. 24:. After the rock-shaft B has carried the embroidering-tubes B between and above the points of the sewing-medles l9 and the pattern-transmitting linger A" has slid such shaft endwise until the embroidering-tubes B have each passed completely ov er the end of one needle 19 and the arm C has descended gravity will cause each embroider ing-tube B to swing backward and return between two needles 19, one being a needle which it passed by in going outward and the other being a needle adjacent thereto, to the position shown in Figs. 15 and 2i, the downward limit of travel of the parts carried by the shaft B".

D, Fig. 9, is a pattern-wheel having a d riving-ratchet D extending around the wriphery thereof and mounted on a stud-bearing l), projecting from a lug D, Figs. 1 and 3, on the machine-frame. The periphery of the pattern-wheel D is provided with three detachable and interchangable pattern-rings l) l) D, adapted to engage and actuate, respectively, the pattern-transmitting lingers A" A A and transmit therethrough their respective patterns to the embroidering devices of the machine.

When the pattern-transmitting linger A is operative and connected with the longitudinally-slidable rock-shaft B, as in Figs. 2 and 2 the carriage A will have no function except to provide a way A", Fig. 22, for such linger A to slide back and forth in and will consequently for the time being remain out of action; but whenever the patterns of either of the pattern-rings D or D 'are required the arm A Fig. 24, will be disengaged from the lug B, which may then be engaged directly with the slot X, Fig. 25, in the slidable earriage A", and either one of the lingers A A may then be engaged with its corresponding pattern-ring, accordin to the pattern desired, in the manner hereinbefore described. The finger A will then lie in and travel idly with the carriage A, which will execute the same backward and forward movements as its operative pattern-transmitting linger, either B or B and communicate them from such operative finger to the longitudinallyslidal)le rock-shaft B. Obviously more than three pattern-rings might be mounted on a. patternwheel if, desired, and a correspondingly-increased number of pattern-transmitting lingers be employed therewith; but inasmuch as the pattern-rings are all detachable and interchangeable no particular advantage would accrue from employing a larger number than are here shown.

The rod D terminates at its left-hand end in a disk D, fast thereto, which is held constantly in contact with the arm D by means of a spring to be described hereinafter.

D is an arm fast by its upper end to the iongitudinally-slidable rod D and provided at its lower end with a fork D engaging the groove C, Fig. 8, in the hub C of the roller C".

D, Fig. 2, is a spring encircling the rod D included between a fixed bearing on the machine-frame and a collar D fast on such rod D Fig. 2 shows the spring D acting through the 'longitudinally-slidable rod D loosely projected end wise against the arm D to maintain the finger D thereof in the path of the actuating-pins D of the pattern-wheel D. The spring D also normally acts, through the rod D and arm D to ship and hold the roller out of engagement with the cam C, which when engaged by and acting through such roller 0, the arms 0 C and cooperating with the force of gravity, oscillates the longitudi-' nally-slidable rock-shaft B and therethrough swings the parts carried thereby up and down.

Whenever the spaces D Fig. 2,'between the radially-projecting lugs D of a pattern; ring, as D", are not too deep, the periphery of such pattern-ring will readily traverse the periphery of the roller A and communicate therethrough its pattern impulses to the pattern-transmitting finger A, whence they will pass interniediately to the longitudinally-sliding rock-shaft B in the manner already hereinbefore explained; but when the spaces be' tween the radially-projecting lugs of any pattern-ring, as D Fig. 22, are too deep to be used successfully with apattern-transmitting finger like A fingers like A A must be em-- ployed. The last-mentioned fingers are identical, and therefore but one of them will be considered here. The form and size of the free end portion of the finger A should be,

such that it will pass freely between any two of the radially-projecting lugs of its patternring in order that the end thereof may contact the bottom of the space between any two such radially: projecting lugs. Obviously, however, if the free end portion of the finger- A Fig. 22, were resting in the bottom of a space, as D between two lugs, as D D on its cam-ring D the finger D would either prevent the rotation of the pattern-wheel D or break it or be itself broken. Mechanismfor obviating the difficulty under considera-, tion will now be described.

The remaining and unlettered parts of the machine (being mainly the devices constituting the narrowing mechanism thereof) should be disregarded. Such parts are shown in the drawings for the reason that they could not well be omitted therefrom without representing the knitting-machine proper too much mutilated to illustrate my invention to the best advantage,as already hereinbefore stated.

At each rotation of the cam D Figs. 2 and 3, the cam E, carried thereby and acting through the roller E and arm E will force the slide E Figs. 9, 22, and 22, upward, thereby causing the cam E thereon to engage the cam E on the carriage A, and there through slide the latter in the direction indicated by the arrow 6, Fig. 9, until the free end of the pattern-transmitting finger A, Fig. 22, is drawn out of the space .1) in its pattern-ring D sufficiently to allow the pallet I) to turn the pattern-wheel D a distance equal to the thickness of one tooth of the ratchet D, when the spring E, Fig. 9, will force the slide E downward to its lowest limit of travel, and the spring E acting through the carriage A will throw the free end of the pattern-transmitting finger A against the end of the lug D" on the pattern-ring D. At the next succeeding rotation of the cams D E a like series of operations will take place, with the result, however, that when the carriage A with its pattern-transmitting finger A is next released by the descent of the slide E the free end of such finger A will slide into and rest against the bottom of the space D Fig. 22, in the cam-ring D and whenever the pattern-ring 1) is to be advanced a notch the pattern-transmitting finger A orA in engagement therewith will be first disengaged therefrom in the manner already described. Fig. 2 shows the cam D engaging theroller D and so long as this engagement continues and such cam is rotated the pallet D will be longitudinally reciprocated and drive the pattern-wheel II). The cam E is also here shown in engagement with the roller E and so long as this engagement continues or the cam E remains in its path and is rotated the slide will be longitudinally reciprocated and the pattern-wheel ,1) will be transmitting a pattern through one of the pattern-transmitting fingers; but until the roller U is engaged by the cam C 'the abovementioned movements of the pattern-wheel I), carriage A and its pattern-tra'nsmitting lingers will be but idle. The actuating-pins D have their inner ends exteriorly threaded to adapt them to be turned into corresponding transverse interiorly-tln'eaded sockets in the pattern-wheel D. The pins D may be arranged and set in a continuous circular series or in segmental groups, as in Fig. 2. ll the pattcrn\\'l1eel l) were provided with a continuous series of actuating-pins l), the operation of embroidering would be continuous;

.but when such pins 1) are arranged in segmental groups, as in Fig. 2, such operation will be intermittent. It the pattern-wheel I) should be now rotated. the pins 1). impinging against the pointot the linger I) of the arm I), and acting therethrough and through the longitudinally-sliding rod 1) and arm I) and against the resistance ol the spring I), would throw the roller into engagement with the cam O on the shaft 10. So long as the point of the finger l)" oi the arm D is being traversed by a circular series or segmental group of pins l) the roller C will continue in engagement with the cam (3.

F, Fig. l, is a stocking in process ot knitting and at the same time having a pattern six times duplicated embroidered thereon. The ornamentation appears on the under side oi the tabric of the stocking F. The length of the pattern to be embroidered will depend upon the number and arrangement of the ttCllllttlJlHQ-Pl ns ll) of the pattern-wheel l) and the extent to which the latter is operated. The width and variations in width of any pattern will depend upon the varying lengths of the riulially-projecting lugs, as 1) I), Fig. 22, of any pattern-ring, as D, and also upon the varying depths of the spaces, as 1), between such lugs.

Supposing the machine to be knitting labrie F which is to be embroidered contemporaneously with its production, the operation of the embroidering mechanism will be as follows: The cam E, acting through the roller E arm E, and extension E" of the slide 1C will force the latter upward against the cam E", Fig. 22, and therethrough slide the carriage A and its pattern-tralismitting linger A in the direction indicated by the arrow w, Fig. 9, until the latter has moved tar enough away from the pattern-ring I), Fig. 22, of the pattern-wheel l) to permit the end of the lug l) thereon to pass upward opposite to and register with the tree end of such linger A. As soon as the linger A" is witlnlrawn from the path of the lug l) the pallet 1)", impelled by the cam 17, acting through the roller D and arm I), will turn the patternwheel vl) one notch, therebycausing the end of the lug l) to pass upward opposite to and register with the free end ol the linger A. The slide IE will then be caused to descend by the action of the spring E, Fig. 5), and the spring F) will thereupon slide the carriage A in the direction indicated by the arrow until it is halted by the free end of the linger A registering and meeting with the end ot the lug D on the pattern-ring l). The lug I), Fig. 22, will now, acting through the pattern-transmitting linger A, its carriage A, and the longitudinally-sliding rock-shaft B and against the resistance of the spring E stop and maintain the embroidering-tubes B in proper positions to carry loops d Fig. 23, of embroidering material, around seven knitting-needles 19 to start the-pattern to be embroideredon v force the arm Fig. 24:, upward against the pintle O which will transmit such upward impulse through the arm 0 to the rock-shaft B and rock the same in the direction indicated by the 'arrow 1 Such rocking of the shaft B acting through the arms B rod B and arms 13, will swing the free ends of the embroidering-tubes B between and a little higher up than the upper ends at, Fig. 15, of the needles 19. The rock-shaft B. Fig. 24L, will continue toswing the embroidering-tubes B still in the direction indicated by the arrow y until the cams B of the disk B are forced up onto the cams B of the disk B as in Fig. 25. The effect of the joint operation of such cams B B is to slide the rock-shaft B endwise a distance equal to thelength of the cams B on the cam: disk B and sufliciently to carry the free end of each embroidering tube B along over across and beyond the top of one needle'19. Thereupon the arm having descended and released the rock -shaft B the spring B Figs. 1 and 2, together with the force of gravity, will swing the embroidering tubes B downward and backward between the needles 19 and will immediately thereafter slide such rock-shaft B embroidering-tubes B and the cam-disk B back endwise to their orginal positions, as in Fig. 24. The dotted line 3 in the diagrammatic view Fig. 23 clearly indi cates the path traveled by the free end of each embroidering-tube B while placing a loop of embroidering material (P, Fig. 23, about 1 one of the needles 19. After seven such loops d have been passed around the proper and a like number of needles 19 a line of thread 0?, Fig. 15, will be paid out by the knittingthread carrier 48, and all the needles 19 of the machine will then knit such thread cl in the manner already described, and the needles about which the loops d Fig. 23, of embroidcry-thread B have been passed will knit such loops (l and their proper portions of the knitting-thread OZ into the fabric F. One stitch Gr, Fig. 21, of embroidery will have been placed on each of the seven designs F, Fig. 1, by the operations just described. The parts of the machine and its embroidering mechanism are now all in position to knit an-" other row of stitches d Figs. 19, 20, and 23, and also to knit into the fabric F, Fig. 1,

seven more embroidery-stitches like G, Fig.

21. As the machine continues to knit G will, be the second stitch embroidered on each of the seven like designs F on the fabric F. Fig.

21 shows the right side of one of the seven designs F being embroidered on the fabric F, and the letters from G to G, inclusive, indicate'by their exponents the order in which the embroidering-stitches are knit into such fabric.
